I have Rocket RS1000's.

Currently I have a 990 connected to a 7700 via balanced connections. That means on the 990 the unbalanced channels are not used. For the powered woofer on the speaker, I want to connect to the 990 via the unbalanced connection.

Seems that if you have a balanced connector being used, that on the 990, it shuts off the unbalanced connections. Is this correct, cause the woofer is producing no sound at all. BOoooooo
